[0024] Figure 1 It is the overall structure schematic diagram of portable propellant decontamination bag according to the utility model embodiment. As Figure 1 The portable propellant decontamination bag includes satchel main body 1, and the satchel main body 1 is equipped with shoulder strap 2. Satchel main body 1 is generally a box structure, is made of hard waterproof synthetic fiber material, including box 11 and box cover 12, and the both ends of shoulder strap 2 are connected to the two sides of box 11 respectively, for operating personnel to wear satchel main body 1 on shoulder. Although Figure 1 Single-shoulder strap design is shown, but the utility model is not limited to this, and double-shoulder strap or other any form of strap that is convenient for staff to wear meets the requirements of the utility model.

[0025] In an embodiment, box 11 and box cover 12 are respectively equipped with first lock component 111 and second lock component 121 that can be locked and unlocked, so that box cover 12 can be locked on box 11, or box cover 12 is opened relative to box 11. For example, first lock component 111 and second lock component 121 constitute press locking mechanism, that is, when first lock component 111 and second lock component 121 are in locking state, by pressing one of the two or third component associated with the two, the locking state between first lock component 111 and second lock component 121 is unlocked.

[0026] Figure 2 It is the top view structural schematic diagram of box 11, Figure 3 It is the side view structural schematic diagram of the part of box 11. As Figure 2 , 3As shown, the satchel body 1 is provided with a propellant concentration monitoring sensor 6, a propellant negative pressure recovery device 3, a decontamination agent spraying device 4, a control unit 5 and a working power supply (not shown). The working power supply can be a rechargeable battery, for example, for providing working voltage for each power consuming unit of the decontamination satchel. The control unit 5 is connected with the propellant concentration monitoring sensor 6, the propellant negative pressure recovery device 3 and the decontamination agent spraying device 4 respectively. The propellant concentration monitoring sensor 6 is used for monitoring propellant concentration in the environment and displaying the monitoring result. The control unit is used for receiving operation instruction from the user and controlling the propellant negative pressure recovery device to recover propellant in the environment and controlling the decontamination agent spraying device to spray decontamination agent to the predetermined area according to the operation instruction.

[0027] The propellant concentration monitoring sensor 6 comprises a display screen 61, a probe 62 arranged at the side of the display screen 61 and an alarm 63. In one embodiment, the propellant concentration monitoring sensor 6 is telescopically arranged at one side of the satchel body. When the propellant concentration monitoring sensor 6 is in the extended state, the probe 62 of the propellant concentration monitoring sensor 6 is exposed to the environment to detect propellant concentration in the environment. When the propellant concentration monitoring sensor 6 is in the retracted state, the probe 62 of the propellant concentration monitoring sensor 6 is hidden in the satchel body 1.

[0028] The display screen 61 is used for displaying propellant concentration detection result of the probe 62. The alarm 63, such as a buzzer and / or a light emitting element, is used for sounding and / or flashing when the propellant concentration detection result exceeds the set threshold. For example, the display screen is a liquid crystal screen, on which specific concentration numerical value of toxic gas such as hydrazine and dinitrogen tetroxide can be displayed. When the concentration numerical value is higher than the set threshold, the alarm flashes and emits a buzzing sound.

[0029] In one embodiment, the propellant concentration monitoring sensor 6 is installed in the satchel body 1 by an elastic locking mechanism (not shown) and a slide rail (not shown). When the propellant concentration monitoring sensor 6 is in the retracted state and an external operation pressure is applied, the elastic locking mechanism is unlocked to push the propellant concentration monitoring sensor to move along the slide rail to the extended state. When the propellant concentration monitoring sensor 6 is in the extended state and an external operation pressure is applied, the propellant concentration monitoring sensor moves along the slide rail to the retracted state and is locked by the elastic locking mechanism. Therefore, the propellant concentration monitoring sensor 6 is arranged in the satchel body 1 in a manner similar to a CD tray, so that it is not necessary to put the sensor in the retracted state when it is working, at which time the probe is hidden in the satchel body 1 to prevent damage from the outside and improve its service life.

[0030] In one embodiment, the power supply circuit of the propellant concentration monitoring sensor 6 comprises a power switch (not shown) arranged on the movement path of the propellant concentration monitoring sensor 6, so that when the propellant concentration monitoring sensor 6 moves from the retracted state to the extended state, the power switch is actuated by the propellant concentration monitoring sensor 6 to be in the on state, and when the propellant concentration monitoring sensor 6 moves from the extended state to the retracted state, the power switch is actuated by the propellant concentration monitoring sensor to be in the off state. Thus, when the sensor does not need to work, the power supply is cut off, avoiding waste of working power supply power of the display screen and the like.

[0031] The propellant negative pressure recovery device 3 comprises a suction device (not shown) arranged in the bag body and a telescopic suction pipe 31 connected with the suction device and extending out of the bag body. The suction device comprises a waste liquid storage bottle (not shown) in communication with the telescopic suction pipe, for storing propellant waste liquid sucked through the telescopic suction pipe. In one embodiment, a measuring device for measuring the concentration of propellant waste liquid is arranged in the waste liquid storage bottle, and the measuring device is connected with the control unit.

[0032] The decontamination agent spraying device 4 comprises a decontamination agent container (not shown) arranged in the bag body and a telescopic spraying pipe 41 connected with the decontamination agent container and extending out of the bag body.

[0033] In the utility model, an air compressor is used as a power source to provide kinetic energy for propellant negative pressure suction and decontamination agent spraying.

[0034] In one embodiment, the portable propellant decontamination bag comprises an air compressor (not shown), the air suction pipe of the air compressor is connected with the propellant negative pressure recovery device 3 to provide kinetic energy for propellant negative pressure suction, and the air outlet pipe of the air compressor is connected with the decontamination agent spraying device 4 to provide kinetic energy for decontamination agent spraying. As an example, the air compressor can be provided with a charging battery.

[0035] In another embodiment, an external air compressor design is used, the portable propellant decontamination bag comprises a first interface connected with the propellant negative pressure recovery device and a second interface connected with the decontamination agent spraying device, the first interface is used to connect the air suction pipe of the air compressor to provide kinetic energy for propellant negative pressure suction, and the second interface is used to connect the air outlet pipe of the air compressor to provide kinetic energy for decontamination agent spraying. When propellant operation with a small moving range is performed, the external design of the air compressor reduces the weight of the bag.

[0036] In use, the propellant concentration monitoring sensor 6 is placed in an extended state, and the probe 62 detects the propellant concentration of the surrounding environment. When the concentration value is higher than the set threshold value, the alarm flashes and emits a beeping sound. The worker controls the propellant negative pressure recovery device 3 and the decontamination agent spraying device 4 to work through the control unit 5 (such as a touch screen).

[0037] Although the utility model has been described in detail through the above embodiments, the utility model is not limited to the above embodiments only, and the technical solutions of the embodiments of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the embodiments of the utility model.
